just wondering. i was debating with a friend of mine. i have heard they will cut and destroy all 5 lugs on a hard launch if you run spacer with 15" draglights/prostars. is this true? he is one of those guys that wont grind like the rest of us! <img border="0" alt="[devil]" title="" src="graemlins/gr_devil.gif" />

also isnt it a 5/16" spacer?

 

I still have to run a thin spacer on the rear of my car, even with my Wilwood rear brakes. The spacers have yet to be a problem, even with my car cutting low 1.3 60' times.

YMMV...

 

I've been having a problem with bent, broken, and crossthreaded lug studs (when using my pro-stars and spacers). I've replaced the rears probably 5 times this year. It was worrying me for a while but I figured it out...

The Pro-Star wheel uses a deep shank style lugnut. Therefore, if you do not get the spacer PERFECTLY centered around the studs when you put on the wheel the lugnut will hit the spacer. Therefore it will be improperly torqued, will crossthread, and 'cause all sorts of ugly problems (like the wheel won't want to come off).

Not like i'd know about this. <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" />

 

i have had to replace one up front and one in the rear. hmmm, does this have to do anything with the wheel itself? i only run spacers up front.

 

I run spacers all the way around (5/16") when I have the draglites on the car. I make sure to center them by hand before snugging down the lugs. Never had any issues for the past 2 years using the draglites.

Diddo to what Nine Ball(Tony) said. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

 

the thicker the wheel spacer, the more leverage it puts on the stud twisting it back and forth.you want more load on the face on the axle resulting in less twist of the stud. wheel spacers arent realy even suppose to pass tech. with a small spacer you should be fine but ide recommend arp studs no matter what. earlier this year i saw a car leave the line break all the studs on one side due to the studs twisting from the wheel spacer, turn sideways, hit the tree and by the time it was done the car was on its side with the tree laying underneath it. all in less then 60 ft.theres my .02 cents. take what you want.

 

PSJ,
I agree with you but Thunder and Madman both said they would not grind anymore on my brakes or they believe that they would become unsafe. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

I do not want to run the 5/16 spacers but I have to with my prostars. I like the look of the Prostars and I do not want to spend the money that it would cost to buy new wheels or brakes. I would rather spend it on more HP! <img border="0" alt="[devil]" title="" src="graemlins/gr_devil.gif" />

Anyway I will get off my soap box now! <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" />

 

ask js12 he put two spacers on.

 

To avoid the mis-aligned spacer problem that bigSS had I just put a few dabs of permatex or similar on the spacers, then press them on the rotor for a minute or two making sure they're perfectly centered. When the permatex sets-up it holds the spacers in place which makes putting the Draglites on & off much easier.

 

Coach, totally true, the center section gets really thin, GeorgeC broke one a while back while grinding... I have kept an eye on mine and so far so good but if I broke one I would get aftermarket rear brakes or different wheels.

 

Snapped 5 lugnuts on a launch using rear spacers on prostars....ground the calipers down the next day and never had a problem with them since.

 

I suggest getting some quality McGuard lug nuts for the Welds.

From my experience... the standard Weld lug nuts are very cheaply made an will eat up your lugs after a few changes.

 

where can we get McGuard lug nuts? maybe i wont suggest using spacers now. <img border="0" title="" alt="[Embarrassed]" src="gr_emb.gif" />

The Summit ones suck too. <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" />

 

very cool to hear guys. maybe i will believe in the wheel spacers after all. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

I can't believe you guys have rear spacers still, I do not. Just grind the outer part of the brake a bit more.

Therefore, the lugs would bottom out before the wheel was tight. If that's the case, would't the wheel shift laterally even without a spacer?

 

Alittle off topic but, is it possible to run the fronts without spacers? I have a set of Telstars that I running 5/16 spacers with and I had to grind the front calipers to get them to fit. I just don't like how they bulge out of the wheel wells.

I have spacers on the front only. I center mine by spraying a little 3M adhesive on there to mate both surfaces. They never move <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
